Hepatitis B vaccination among a national sample of gay and bisexual men

Hepatitis A and B vaccination in gbMSM in Ireland: findings from the European MSM Internet Survey 2017 (EMIS-2017)

OBJECTIVES

Gay, bisexual and other men who have sex with men (gbMSM) have a higher risk of acquiring hepatitis A and B viruses (HAV and HBV) than the general population and are recommended for vaccination against both in Ireland. This study aims to determine the prevalence of self-reported HAV and HBV infection and vaccination among gbMSM in Ireland and explore factors associated with self-reported HAV and HBV vaccination among gbMSM.

METHODS

This study analysed Irish data from the European MSM Internet Survey 2017 (EMIS-2017) to measure the prevalence of self-reported HAV and HBV infection and vaccination among gbMSM in Ireland. Multivariable logistic regression was used to explore the associations between sociodemographic, healthcare-related and behavioural factors and self-reported vaccination.

RESULTS

There were 2083 EMIS-2017 respondents in Ireland. Among HIV-negative gbMSM, 4.6% and 4.4% reported previous HAV and HBV infection, respectively, and 51% and 57% reported the receipt of one or more vaccine dose for HAV and HBV, respectively. In the multivariable analysis, HIV-negative gbMSM had lower odds of self-reported HAV vaccination if they lived outside the capital, Dublin (aOR 0.61, 95% CI: 0.48 to 0.78), had no third-level education (aOR 0.65, 95% CI: 0.45 to 0.92), were not tested for HIV in the last year (aOR 0.39, 95% CI: 0.31 to 0.50), had never tried to obtain pre-exposure prophylaxis (PrEP, aOR 0.60, 95% CI: 0.38 to 0.96) and had not been diagnosed with a sexually transmitted infection (STI) in the previous year (aOR 0.42, 95% CI: 0.28 to 0.63). Similar associations were observed for self-reported HBV vaccination.

CONCLUSIONS

Self-reported vaccination against HAV and HBV among gbMSM in Ireland is high, but the level of vaccination remains insufficient to protect against future HAV and HBV infections and outbreaks. Efforts to increase vaccination coverage among gbMSM should focus on men who live outside the capital, have lower educational attainment and do not engage with sexual health services.

Sexual Orientation and Gender Identity Differences in Influenza, Shingles, and Pneumococcal Vaccination Among U.S. Older Adults

Purpose: LGBT older adults face challenges accessing and receiving culturally competent health care and may be more vulnerable to serious outcomes from vaccine-preventable diseases. This study examines whether sexual orientation and gender identity are associated with older adult influenza, zoster ("shingles"), and pneumococcal vaccine uptake. Methods: Data come from the 2020 Behavioral Risk Factor Surveillance System. The sample included older adults aged 50+ (eligible for influenza and shingles vaccination; n = 136,528) and 65+ (eligible for pneumococcal vaccination; n = 74,779). We calculated rates of influenza, shingles, and pneumococcal vaccine uptake by gender-stratified sexual orientation groups and for transgender versus cisgender populations. Logistic regression models tested for associations between sexual orientation, gender identity, and vaccine uptake, controlling for key sociodemographic characteristics. Results: Transgender adults had the lowest rates of uptake across all three vaccines, including 46% lower odds of shingles vaccination and 61% lower odds of pneumococcal vaccination, when compared with cisgender adults. Gay (vs. straight) men had 1.5-1.9 times greater odds of flu and shingles vaccination. Bisexual (vs. straight) women had 32% lower odds of flu vaccination. Conclusion: Our findings indicate that vaccine uptake among LGBT older adults varies by sexual orientation, gender identity, and vaccine type. Bisexual women and transgender people are groups that tend to underutilize health care services and are at increased risk of nonvaccination, making them important targets for older adult vaccine promotion.

Digestive Health in Sexual and Gender Minority Populations

It has been over 50 years since the Stonewall Inn Riots in June 1969, a seminal event for the lesbian, gay, bisexual, transgender, queer, intersex, and other sexual and gender-diverse minorities (LGBTQI+, or lesbian, gay, bisexual, transgender, queer, intersex, and everyone else) rights movement. However, sexual and gender minority (SGM) individuals still face discrimination and harassment due to their sexual orientation or gender identity. As such, the National Institute on Minority Health and Health Disparities has identified SGM communities as a "health disparity population." Broadly, there are higher rates of sexually transmitted infections, substance use and abuse, mental health conditions, obesity and eating disorders, certain cancers (breast, cervical, and anorectal), and cardiovascular disease in SGM communities. Transgender patients, especially those of color, are more likely to be uninsured, experience discrimination, and be denied health care than cisgender patients. In addition, SGM individuals have twice the risk of lifetime exposure to emotional, physical, and sexual trauma compared with heterosexuals. It is expected all these factors would negatively affect digestive health as well. This review summarizes the effects of social determinants of health and discrimination on health care access, highlights important digestive diseases to consider in the SGM population, and offers solutions to improve and prioritize the health of these communities. We aim to draw attention to SGM-specific issues that affect gastrointestinal health and spur research that is desperately lacking.

Human papillomavirus (HPV) vaccination across a cascade of knowledge, willingness, and uptake among gay, bisexual, and other men who have sex with men in Canada's three largest cities

BACKGROUND

Some Canadian jurisdictions offer publicly funded HPV vaccine to gay, bisexual, and other men who have sex with men (GBM) aged ≤26 years. We characterized factors associated with being in different stages of HPV vaccination.

METHODS

Engage is a sexual health study of GBM in the three largest Canadian cities recruited via respondent driven sampling (RDS). We categorized participants as: (1) unaware of HPV vaccine, (2) undecided/unwilling to get vaccinated, (3) willing to get vaccinated, (4) vaccinated with one or more doses. Our RDS-II weighted analyses used multinomial logistic regression to identify factors associated with being in earlier stages of the cascade compared to Stage 4.

RESULTS

Across the cities, 26-40%, 7-14%, 33-39%, and 13-28% were in Stages 1 to 4, respectively. Compared to Stage 4, being in earlier stages of the cascade was associated with bisexual-identification (Stage 1: adjusted odds ratio[aOR] = 2.84, 95% confidence interval[CI] = 1.06-7.62; Stage 2: aOR = 3.09, 95%CI = 1.19-8.05), having immigrated to Canada (Stage 1: aOR = 1.79, 95%CI 1.07-2.99), preference to keep same-sex romantic relationships private (Stage 1: aOR = 1.25, 95% CI = 1.05-1.48; Stage 2: aOR = 1.24, 95%CI = 1.05-1.46), not receiving sexual health information (Stage 1: aOR = 0.31, 95% CI = 0.13-0.71; Stage 2: aOR = 0.27, 95%CI = 0.12-0.64), not accessing a health-care provider (Stage 2: aOR = 0.36, 95%CI = 0.15-0.83), and no past hepatitis A/B vaccination (Stage 1: aOR = 0.16, 95% CI = 0.09-0.30; Stage 2: aOR = 0.18, 95%CI = 0.09-0.35; Stage 3: aOR = 0.38, 95%CI = 0.21-0.61).

DISCUSSION

Interventions are needed to reduce social and financial barriers, increase sexual health knowledge, and improve GBM-competent health-care access to increase vaccine uptake among GBM.

Acute Hepatitis A and Hepatitis B Coinfection

Hepatitis A (HAV) has emerged in outbreaks across the United States particularly in at-risk populations such as men who have sex with men, as well as patients with a history of drug use, homelessness, and incarceration. Immunization among these high-risk populations remains underused. In this study, we describe a case of acute HAV and hepatitis B (HBV) coinfection in an MSM patient occurring in the period of these outbreaks. Clinical resolution of acute HAV and HBV coinfection was attained by 5 months from the time of initial hospitalization without viral hepatitis treatment. This case highlights the need for increased awareness of at-risk populations for HAV and HBV infection in promoting guideline-based vaccination efforts.

Vaccine acceptability, uptake and completion amongst men who have sex with men: A systematic review, meta-analysis and theoretical framework

BACKGROUND

Due to an increased risk of sexually transmitted infections (STIs), gay, bisexual and other men who have sex with men (MSM) have been recommended to receive vaccinations against human papillomavirus, meningitis C and hepatitis A/B. This review aimed to compare the rates of vaccine acceptability, uptake and completion, and to identify determinants of vaccine outcomes specific to MSM to inform a theoretical framework.

METHODS

In January 2020 four databases were explored to identify vaccination behaviours and associated factors among MSM. A narrative systematic review and meta-analysis were performed. Data were synthesised for theoretical modelling.

RESULTS

Seventy-eight studies, mostly from the USA, were included. The average vaccine acceptability was 63% (median = 72%, range: 30%-97%), vaccine uptake 45% (median = 42%, range: 5%-100%) and vaccine completion 47% (median = 45%, range: 12%-89%). Six categories of factors associated with vaccination acceptability, uptake and completion were conceptualised: Individual (e.g., demographic and psychosocial); Interpersonal (e.g., peer education); Healthcare provider (e.g., vaccine recommendation); Organisational and practice setting (e.g., routine collection of patient sexual orientation information that is integrated into a clinical decision support system); Community environment (e.g., targeted health promotion campaigns); and National, state and local policy environment (e.g., public health guidelines targeting MSM).

CONCLUSION

Despite overall high levels of acceptability, uptake and completion rates were below targets predicted by cost-effectiveness modelling across all recommended vaccines. These parameters may need to be adjusted for more precise estimations of cost-effectiveness. Addressing the multiple levels of determinants, as outlined in our theoretical framework, will help guide interventions to increase vaccine completion among MSM.

Understanding influenza immunization uptake rates among the Hispanic LGBTQIA community

OBJECTIVES

Most national-level data regarding lesbian, gay, bisexual, transgender, queer/questioning, intersex, and allies (LGBTQIA) immunizations are limited. The primary objective of this study was to identify factors that influence behaviors, attitudes, and perceptions toward the uptake of the influenza vaccine within the Hispanic LGBTQIA community.

METHODS

This was a prospective survey that assessed vaccine acceptability and practices regarding the influenza vaccine within the LGBTQIA community. Collection of data occurred through the use of social media platforms from July 2016 to May 2018. A total of 126 participants (mean age 32.03 ± 11.68 years) completed a 15-minute, 26-item, English/Spanish survey. A number of outcome measures assessed perceptions of vaccine effectiveness and safety. In addition, perceived severity of influenza symptoms and perceived susceptibility to contract influenza was assessed.

RESULTS

A logistic regression model assessed the impact of several factors on influenza vaccine uptake. Perceived susceptibility of contracting influenza from the vaccine (P = 0.015) and perceived ease of receiving the influenza vaccine (P = 0.005) were the strongest predictors of vaccine uptake. Results showed no association between disclosure of sexual orientation and influenza immunization uptake (χ²= 3.55; P = 0.17). Exploratory analyses revealed that non-Hispanic patients were more likely to perceive that their health care providers were aware of their sexual orientation compared with Hispanic patients (χ²= 8.66; P = 0.013).

CONCLUSION

Several factors emerged as predictors of influenza vaccine uptake in the LGBTQIA population. Further studies are needed to explore additional factors such as disclosure of sexual orientation and variation of uptake based on vaccine type (STD vs. non-STD vaccines).

Vaccination differences among U.S. adults by their self-identified sexual orientation, National Health Interview Survey, 2013-2015

Introduction

Very few studies have explored the associations between self-identified sexual orientation and comprehensive vaccination coverage. Most of the previous studies that reported health disparities among lesbian, gay and bisexual populations were not based on a nationally representative sample of U.S. adults, limiting the generalizability of the findings. Starting in 2013, the National Health Interview Survey (NHIS) included questions to ascertain the adult’s self-identified sexual orientation that allowed national level vaccination estimation by sexual orientation. This study examined associations of self-reported vaccination coverage for selected vaccines among U.S. adults by their sexual orientation.

Methods

We analyzed combined data from 2013–2015 NHIS, a nationally representative probability-based health survey of the noninstitutionalized U.S. population ≥18 years. For vaccines other than influenza, weighted proportions were calculated. Influenza coverage was calculated using the Kaplan-Meier procedure. Multivariable logistic regression models were used to calculate adjusted prevalence differences for each vaccine overall and stratified by sexual orientation and to identify factors independently associated with vaccination.

Results

Significant differences were observed by sexual orientation for self-reported receipt of human papillomavirus (HPV), hepatitis A (HepA), hepatitis B (HepB), and influenza vaccination. Bisexual females (51.6%) had higher HPV coverage than heterosexual females (40.2%). Gay males (40.3% and 53.6%, respectively) had higher HepA and HepB coverage than heterosexual males (25.4% and 32.6%, respectively). Bisexual females (33.9% and 58.5%, respectively) had higher HepA and HepB coverage than heterosexual females (23.5% and 38.4%, respectively) and higher HepB coverage than lesbian females (45.4%). Bisexual adults (34.1%) had lower influenza coverage than gay/lesbian (48.5%) and heterosexual adults (43.8%). Except for the association of having self-identified as gay/lesbian orientation with greater likelihood of HepA, HepB, and influenza vaccination, sexual orientation was not associated with higher or lower likelihood of vaccination. Health status or other behavioral characteristics studied had no consistent relationship with vaccination among all populations.

Conclusion

Differences were identified in vaccination coverage among the U.S. adult population by self-reported sexual orientation. This study is the first to assess associations of sexual orientation with a comprehensive list of vaccinations. Findings from this study can serve as a baseline for monitoring changes over time. All populations could benefit from improved vaccination.

Hepatitis B Vaccination and Infection Prevalence Among Men Who Have Sex With Men Who Travel Internationally

Among men who have sex with men traveling internationally, self-reported hepatitis B virus (HBV) vaccination prevalence was 77% and less prevalent among older men and those with HBV infection. The HBV infection prevalence was 25% and was associated with older age and HIV infection. Testing for chronic infection, universal vaccination, and treatment for populations with multiple risks is needed.

Disclosure of Sexual Orientation and Uptake of HIV Testing and Hepatitis Vaccination for Rural Men Who Have Sex With Men

PURPOSE

The decision and ability of primary care clinician to make recommendations for routine human immunodeficiency virus (HIV) testing and hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccines are shaped by knowledge of their patient's risk behaviors. For men who have sex with men, such knowledge requires disclosure of same-sex sexual behavior or sexual identity.

METHODS

Data were analyzed from a national survey of rural men who have sex with men (N = 319) to understand whether the disclosure of sexual identity to clinicians was associated with increased uptake of HIV testing and hepatitis vaccinations.

RESULTS

We found that disclosure of sexual identity to clinicians was significantly associated (OR = 1.26; 95% CI, 1.08-1.47) with uptake of routine HIV testing and HAV/HBV vaccination.

CONCLUSION

Our finding reinforces the need for safe, nonjudgmental settings for patients to discuss their sexual identities freely with their clinicians.

Hepatitis B vaccination uptake and correlates of serologic response among HIV-infected and uninfected men who have sex with men (MSM) in Bangkok, Thailand

BACKGROUND

Vaccination against hepatitis B virus (HBV) is recommended for all HBV-susceptible men who have sex with men (MSM). There is limited information on correlates of immunity to HBV vaccination in this group. We present serologic response rates to hepatitis B vaccine and identify factors associated with impaired response among HIV-uninfected and HIV-infected Thai MSM.

METHODOLOGY

HBV-susceptible volunteers were offered hepatitis B vaccination at months zero, one, and six. We measured baseline (pre-vaccination) total serum IgG and IgG subclasses (all participants), baseline CD4 count, and plasma HIV-1 viral load (PVL) (HIV+ participants). HBV serologies were retested at 12 months. Serologic responses were compared between all groups in men receiving three vaccine doses.

RESULTS

511/651 HIV-negative and 64/84 HIV-positive participants completed the three-dose series. Response rates in HIV-uninfected and -infected participants were 90.1% vs. 50.0% (p<0.0001). Median pre-vaccination IgG was higher among non-responders than responders overall (1238.9.0 vs. 1057.0mg/dL, p=0.003) and among HIV-infected participants (1534.0 vs. 1244.5mg/dL, p=0.005), but not significantly among HIV-uninfected participants (1105.5 vs. 1054.3mg/dL, p=0.96). Pre-vaccination IgG1 and IgG3 levels were higher among HIV-positive than HIV-negative participants (median 866.0 vs. 520.3, and 105.8 vs. 83.1mg/dL, respectively, p<0.0001). Among HIV-infected participants, median CD4 count in non-responders was 378 cells/μL vs. 431 cells/μL in responders (p=0.20). Median PVL in non-responders was 64,800 copies/mL vs. 15500 copies/mL in responders (p=0.04). Participants with pre-vaccination plasma IgG >1550 mg/dL and PVL >10,000 copies/mL were almost always non-responsive (p<0.01).

CONCLUSIONS

HIV infection was associated with poor vaccine responses. High plasma viral load, elevated pre-vaccination total serum IgG and elevated pre-vaccination IgG1 are associated with poorer response to vaccination among HIV-infected MSM. In this group, the combination of high PVL and pre-vaccination total IgG is highly predictive of vaccine failure.

HPV vaccination for MSM: Synthesis of the evidence and recommendations from the Québec Immunization Committee

Diseases associated with the human papilloma virus (HPV) are particularly common among men who have sex with men (MSM). Unlike heterosexual men, MSM do not benefit from the herd protection provided by the vaccination of girls. In this review, we synthesize the available evidence on HPV vaccination for MSM. We also present the recommendations of the Québec Immunization Committee (CIQ) in this regard, which are: to provide targeted vaccination for MSM up to 26 years of age and in-school vaccination of preadolescent boys since this is the best approach to take to have a real impact on the burden related to HPV in the MSM population and to provide direct protection for all men.

Coverage of the 2011 Q fever vaccination campaign in the Netherlands, using retrospective population-based prevalence estimation of cardiovascular risk-conditions for chronic Q fever

Background

In 2011, a unique Q fever vaccination campaign targeted people at risk for chronic Q fever in the southeast of the Netherlands. General practitioners referred patients with defined cardiovascular risk-conditions (age >15 years). Prevalence rates of those risk-conditions were lacking, standing in the way of adequate planning and coverage estimation. We aimed to obtain prevalence rates retrospectively in order to estimate coverage of the Q fever vaccination campaign.

Methods

With broad search terms for these predefined risk-conditions, we extracted patient-records from a large longitudinal general-practice research-database in the Netherlands (IPCI-database). After validation of these records, obtained prevalence rates (stratified for age and sex) extrapolated to the Q fever high-incidence area population, gave an approximation of the size of the targeted patient-group. Coverage calculation addressed people actually screened by a pre-vaccination Q fever skin test and serology (coverage) and patients referred by their general practitioners (adjusted-coverage) in the 2011 campaign.

Results

Our prevalence estimate of any risk-condition was 3.1% (lower-upper limits 2.9-3.3%). For heart valve defects, aorta aneurysm/prosthesis, congenital anomalies and endocarditis, prevalence was 2.4%, 0.6%, 0.4% and 0.1%, respectively. Estimated number of eligible people in the Q fever high-incidence area was 11,724 (10,965-12,532). With 1330 people screened for vaccination, coverage of the vaccination campaign was 11%. For referred people, the adjusted coverage was 18%. Coverage was lowest among the very-old and highest for people aged 50–70 years.

Conclusion

The estimated coverage of the vaccination campaign was limited. This should be interpreted in the light of the complexity of this target-group with much co-morbidity, and of the vaccine that required invasive pre-vaccination screening. Calculation of prevalence rates of risk-conditions based on the IPCI-database was feasible. This procedure proved an efficient tool for future use, when prevalence estimates for policy, implementation or surveillance of subgroup-vaccination or other health-care interventions are needed.

Vaccinating sons against HPV: results from a U.S. national survey of parents

Purpose

The quadrivalent HPV vaccination was approved for use in males ages 9 to 26 in 2009 and recommended for routine administration in 2011. The purpose of this study was to uncover predictable commonalities amongst parents who chose to vaccinate their 11–17 year old sons against HPV.

Methods

We compiled data from a U.S. national sample of 779 parents with sons 11–17 years old using a web-based survey to gather information about behavioral and sociodemographic factors which predicted receipt of 1 or more HPV vaccine doses based on parental report. Predictors were first modeled individually for univariable associations. Significant predictors (p<0.10) were combined in a multivariable model.

Results

In the adjusted model, independent predictors included receipt of flu vaccination, health insurance coverage and sexual health topic discussions with sons. Sons who had received a flu shot in the last two years more frequently received at least one dose of the vaccine (OR 1.82; 95% CI 1.45–2.26). Sons covered by private health insurance had decreased odds of HPV vaccination (OR 0.56 95% CI 0.37–0.83). Lastly, parents who had discussed sexual health topics with their sons were more likely to vaccinate (OR 1.61; 95% CI 1.37–1.89).

Conclusions

Male vaccination rates in the U.S. have increased, but males continue to be under-immunized. Utilization of health care is an important factor in HPV vaccine uptake; therefore, health care providers should use every contact as an opportunity to vaccinate. Communication about sexual health topics may provide a forum for parents and health care providers to have conversations about HPV vaccination as those more comfortable discussing these topics may also be more comfortable discussing HPV vaccination.

Hepatitis B virus (HBV) infection, immunity and susceptibility among men who have sex with men (MSM), Los Angeles County, USA

Men who have sex with men (MSM) bear a disproportionate burden of hepatitis B virus (HBV) infections. We used serologic data from the National HIV Behavioral Surveillance (NHBS) system to determine the prevalence and correlates of HBV infection, immunization, and susceptibility in a sample of Los Angeles County MSM. Approximately 19 % (95 % CI 15-24 %) had serologic evidence of current or past infection, while 35 % (95 % CI 30-40 %) were susceptible. Compared with the youngest age group, MSM ages 40-49 years had a lower prevalence of immunization (aPR 0.28, 95 % CI 0.17-0.45) and a higher prevalence of infection (aPR 8.53, 95 % CI 3.95-18.4) and susceptibility (aPR 2.02, 95 % CI 1.13-3.63). We also observed poor concordance between self-reported and serologic measures of vaccination. Our results indicate the possibility of missed opportunities to vaccinate MSM. Gaps in implementing existing vaccination strategies must be addressed to increase hepatitis B vaccination coverage for MSM, especially in older age groups.

Disparities and risks of sexually transmissible infections among men who have sex with men in China: a meta-analysis and data synthesis

Background

Sexually transmitted infections (STIs), including Hepatitis B and C virus, are emerging public health risks in China, especially among men who have sex with men (MSM). This study aims to assess the magnitude and risks of STIs among Chinese MSM.

Methods

Chinese and English peer-reviewed articles were searched in five electronic databases from January 2000 to February 2013. Pooled prevalence estimates for each STI infection were calculated using meta-analysis. Infection risks of STIs in MSM, HIV-positive MSM and male sex workers (MSW) were obtained. This review followed the PRISMA guidelines and was registered in PROSPERO.

Results

Eighty-eight articles (11 in English and 77 in Chinese) investigating 35,203 MSM in 28 provinces were included in this review. The prevalence levels of STIs among MSM were 6.3% (95% CI: 3.5–11.0%) for chlamydia, 1.5% (0.7–2.9%) for genital wart, 1.9% (1.3–2.7%) for gonorrhoea, 8.9% (7.8–10.2%) for hepatitis B (HBV), 1.2% (1.0–1.6%) for hepatitis C (HCV), 66.3% (57.4–74.1%) for human papillomavirus (HPV), 10.6% (6.2–17.6%) for herpes simplex virus (HSV-2) and 4.3% (3.2–5.8%) for Ureaplasma urealyticum. HIV-positive MSM have consistently higher odds of all these infections than the broader MSM population. As a subgroup of MSM, MSW were 2.5 (1.4–4.7), 5.7 (2.7–12.3), and 2.2 (1.4–3.7) times more likely to be infected with chlamydia, gonorrhoea and HCV than the broader MSM population, respectively.

Conclusion

Prevalence levels of STIs among MSW were significantly higher than the broader MSM population. Co-infection of HIV and STIs were prevalent among Chinese MSM. Integration of HIV and STIs healthcare and surveillance systems is essential in providing effective HIV/STIs preventive measures and treatments.

Implementation of an electronic medical record does not change delivery of preventive care for HIV-positive patients

PURPOSE

This study sought to determine the impact that an electronic medical record (EMR) had on the provision of preventive health measures - including obtaining serologies for viral hepatitis and administering vaccinations to non-immune patients - to HIV patients at a hospital-based clinic.

METHODS

Using a pre-post study design, we compared rates of preventive health delivery to HIV patients at an outpatient clinic during the use of a paper medical record (PMR) and after implementation of an EMR. Retrospective chart reviews were conducted at two time points: 12-16 months prior to and 24 months following EMR implementation. The records of 160 active patients were randomly selected for review during both time periods.

RESULTS

There was no difference between the PMR and EMR samples with regard to the proportion of patients who had hepatitis A (83% in PMR group; 77% in EMR) and hepatitis C (94% in both groups) serologies measured or the proportion of eligible patients who were given hepatitis vaccinations. Slightly fewer patients had a serology for hepatitis B measured in the EMR sample.

CONCLUSIONS

As EMR implementation expands, it is important to evaluate the effects that EMRs have on patient outcomes, including preventive health provision. Our study showed that after implementation of an EMR, the provision of most preventive care measures did not improve. This finding is in agreement with many published studies. Some studies have found positive effects from EMRs that may be attributable to specific aspects of EMRs. Further study of the effect of specific EMR attributes on health care outcomes is needed.

Australian sexually transmissible infection and HIV testing guidelines for asymptomatic men who have sex with men 2014: a review of the evidence

Men who have sex with men (MSM) in Australia and overseas are disproportionately affected by sexually transmissible infections (STIs), including HIV. Many STIs are asymptomatic, so regular testing and management of asymptomatic MSM remains an important component of effective control. We reviewed articles from January 2009–May 2013 to inform the 2014 update of the 2010 Australian testing guidelines for asymptomatic MSM. Key changes include: a recommendation for pharyngeal chlamydia (Chlamydia trachomatis) testing, use of nucleic acid amplification tests alone for gonorrhoea (Neisseria gonorrhoeae) testing (without gonococcal culture), more frequent (up to four times a year) gonorrhoea and chlamydia testing in sexually active HIV-positive MSM, time required since last void for chlamydia first-void urine collection specified at 20 min, urethral meatal swab as an alternative to first-void urine for urethral chlamydia testing, and the use of electronic reminders to increase STI and HIV retesting rates among MSM.

Selective hepatitis B virus vaccination has reduced hepatitis B virus transmission in the Netherlands

BACKGROUND & AIMS

In the Netherlands, a selective hepatitis B virus (HBV) vaccination programme started in 2002 for men having sex with men, drug users, commercial sex workers and heterosexuals with frequent partner changes. We assessed the programme's effectiveness to guide policy on HBV prevention.

METHODS

We analysed reports of acute HBV infection in the Netherlands between 2004 and 2010 requesting serum from patients for HBV-genome S- and C-region sequencing. We used coalescence analyses to assess genetic diversity of nonimported genotype-A cases over time.

RESULTS

1687 patients with acute HBV infection were reported between 2004 and 2010. The incidence of reported acute HBV infection decreased from 1.8 to 1.2 per 100,000 inhabitants, mostly due to a reduction in the number of cases in men who have sex with men. Men were overrepresented among cases with an unknown route of transmission, especially among genotype A2 cases mainly associated with transmission through male homosexual contact. The genetic diversity of nonimported genotype-A strains obtained from men who have sex with men decreased from 2006 onwards, suggesting HBV incidence in this group decreased.

CONCLUSIONS

The selective HBV-vaccination programme for behavioural high-risk groups very likely reduced the incidence of HBV infection in the Netherlands mainly by preventing HBV infections in men who have sex with men. A considerable proportion of cases in men who did not report risk behaviour was probably acquired through homosexual contact. Our findings support continuation of the programme, and adopting similar approaches in other countries where HBV transmission is focused in high-risk adults.

HIV, hepatitis and syphilis prevalence and correlates of condom use during anal sex among men who have sex with men in the Republic of Moldova

Limited data on HIV prevalence and related risks among men who have sex with men (MSM) exist in the Republic of Moldova. In Chisinau and Balti, 188 and 209, respectively, men who reported having anal or oral sex in the last six months with another man, aged ≥16 years were recruited into a study in 2010 using respondent-driven sampling methods. MSM reported having multiple male and female partners and inconsistent condom use. In Chisinau, 2% of MSM were HIV seropositive, 3.7% had antibodies to hepatitis C (HCV), 5.7% had antibodies to hepatitis B (HBV) and 12.1% had syphilis. In Balti, less than 1% of MSM were HIV seropositive, 1.2% had antibodies to HCV, 3.2% had antibodies to HBV and only 0.5% had syphilis. MSM who used a condom at last anal sex with a man were less likely to reside in Chisinau, to have casual sex partners and to have had an HIV test in the last year and were more likely to know where to get an HIV test. Although HIV prevalence was low, MSM practice a number of risky sexual behaviours that may heighten the risk of further HIV transmission in this population and to the wider population.
